Re^5: How would I sort a two-dimensional array by multiple columns?

While I like your solution, FunkyMonk's routine could be made to sort on all elements of an array by changing its arguments:

my $sorted = FunkyMonkSort($unsorted, 0..$#$unsorted);

Your code meets the specification to sort a 2D array where each element in every row is compared.

FunkyMonk's code solves a different problem--sort a 2D array by an arbitrary subset of elements in each row.

I spent a while looking for the "bug". There really isn't a bug, it's just that you interpreting the spec differently than FunkyMonk did.

BTW, I like the way that you called attention the the fact the NetWallaSort() is a sort function, and gets $a and $b automagically.

TGI (++)- Agreed to all your points. I had /msg'd FunkyMonk (also ++) that I had misread the OP's requirement. I now publicly post that his post was NOT buggy, based on what the OP said he wanted, and his "@_" was indeed what he intended (after his update). "As you get older three things happen.
